     where 
     C 3  H 5  (OH) represents the structures: ##STR1## R F  represents a perfluorinated C 4  -C 20  alkyl radical or a mixture of perfluorinated C 4  -C 20  alkyl radicals;

This application is a 371 of PCT/FR94 00633 filed on Jun. 1, 1994.

The present invention concerns the use of hydro- and fluorocarbon compounds in cosmetic compositions, cosmetic compositions containing these compounds and certain hydro- and fluorocarbon sulfoxides or sulfones.

Perfluoropolyethers are known for their use in cleaning, protecting or making up the skin or washing hair. These compounds are known to have a low surface tension and are easy to spread, but have very low solubility in most fluids apart from fluorine-containing fluids. This means that they are difficult to incorporate in cosmetic composition formulations. Some of these compounds, perfluoromethylisopropylethers, are sold by MONTEFLUO under the trade name "FOMBLIN HC".

We have now discovered compounds which, contrary to FOMBLIN compounds, have good solubility properties, in particular in the conventional solvents used in cosmetics, such as low alcohols, fatty substances and the usual oils. Their amphiphilic character, properties and compatibility with the solvents mean that homogeneous, stable compositions can be prepared and, for example, can ensure that the emulsions they form have good stability.

The present invention thus concerns the use of compounds with formula:

    R.sub.F --(CH.sub.2).sub.n --X-- C.sub.3 H.sub.5 (OH)!--Y--R.sub.H(I)

where

C₃ H₅ (OH) represents the structures: ##STR3## R_(F) represents a perfluorinated C₄ -C₂₀ alkyl radical or a mixture of perfluorinated C₄ -C₂₀ alkyl radicals;

R_(H) represents a linear or branched C₁ -C₂₂ alkyl radical or a mixture of linear or branched C₁ -C₂₂ alkyl radicals, an aryl radical or an aralkyl radical;

n is between 0 and 4;

X and Y represent S, ##STR4## in a cosmetic composition.

Preferred compounds are those for which R_(F) represents a perfluorinated C₆ -C₁₂ alkyl radical, R_(H) represents a linear or branched C₃ -C₁₈ alkyl radical, a C₆ -C₁₀ aryl radical or a C₇ -C₁₅ aralkyl radical, and n equals 2.

Preferably, X and Y represent S.

Examples of linear or branched alkyl radicals are butyl, octyl, 2-ethylhexyl, decyl, dodecyl, 2-butyloctyl, hexadecyl, 2-hexyldecyl, and octadecyl radicals.

Examples of aralkyl radicals are 4-nonylphenyl and benzyl radicals, and an example of an aryl radical is the phenyl radical.

Compounds with formula (I) in accordance with the invention can be prepared by reacting a fluorine compound containing an acidic hydrogen with formula (II):

    R.sub.F --(CH.sub.2).sub.n --S--H                          (II)

with an epoxide with formula (III): ##STR5## or by reacting a hydrocarbon containing an acidic hydrogen with formula (IV):

    R.sub.H --S--H                                             (IV)

with a fluorine-containing epoxide with formula (V): ##STR6## in the presence of an acidic or basic compound which acts as a reactant or as a catalyst, to produce the corresponding compound with formula (I). Substituents R_(F), R_(H) and n have the same meanings in formulae (II), (III), (IV) and (V) as those given for formula (I). The mercaptan function can be optionally oxidized to the sulfoxide or sulfone using an oxidizing agent, preferably hydrogen peroxide in an acidic medium.

Compounds with formula (V) are described in U.S. Pat. 3,976,698, in European patent application EP-A-0 300 358 and in German patent application DE-A-2 018 461.

The compounds which act as a reactant or as a catalyst may thus be basic, such as alkali metals, alkali or alkaline earth metal hydroxides, alkali metal alcoholates such as methylates or tertiobutylates, alkaline hydrides such as sodium hydride, or tertiary amines such as pyridine or triethylamine. They may also be Lewis bases, for example cesium, rubidium or potassium fluorides. These compounds may be supported on a solid support such as alumina. Preferably, an alkali alcoholate such as sodium methylate or a tertiary amine such as pyridine is used.

These compounds may also be acids, in particular when the starting material with formula (II) or (IV) is an alcohol. These acids may be inorganic acids or their tertiary amine salts, or Lewis acids such as boron trifluoride, tin tetrachloride, or antimony pentachloride, used neat, in solution or associated with any normal support.

A basic compound is preferably used.

The concentration of acid or basic compounds acting as reactant or catalyst and used in preparing compounds with formula (I) can be between 1% and 100% molar, preferably between 2% and 10% molar with respect to the fluorine-containing compound with an acidic hydrogen with formula (II) or (IV).

The preparation can be carried out in the presence or absence of a solvent.

Examples of solvents are aliphatic hydrocarbons such as heptane or hexane, cyclic hydrocarbons such as cyclohexane, aromatic hydrocarbons such as toluene, ethers such as ethyl ether or isopropyl ether, cyclic ethers such as dioxane, or acetonitrile, dimethylformamide, N-methylpyrrolidone, dimethylacetamide or alcohols such as methanol, ethanol or isopropanol.

The compound of the invention can be prepared by firstly mixing the compound with an acidic hydrogen with formula (II) or (IV) with the acidic or basic reactant or catalyst, in an inert atmosphere. Mixing can be carried out at a temperature of between 20° C. and 180° C., preferably between 50° C. and 150° C. The term "inert atmosphere" means an atmosphere of nitrogen, argon or helium, for example.

Mixing can be effected in the presence or absence of a solvent, depending on the nature of the compound with an acidic hydrogen and the reactant or catalyst.

The epoxide with formula (III) or (V) is then added to the mixture obtained. Addition can be effected all at once or gradually, over a period of 30 minutes to 2 hours, for example.

The reaction time is thus between about 1 hour and 24 hours, preferably between 1 hour and 3 hours.

When it contains a mercaptan function, the compound produced by the reaction can be oxidized to a sulfoxide or sulfone in the presence of hydrogen peroxide in an acidic medium, using known methods, particularly as described in French patents FR-A-2 099 092 and FR-A-2 516 920.

It may also be necessary to neutralize the mixture obtained, and separate the synthesized compound using conventional methods, for example distillation.

When a compound with formula (I) is prepared in the presence of a basic compound, it produces only compounds in which C₃ H₅ (OH) represents group (Ia). When the reaction is carried out in the presence of an acidic compound, a mixture of compounds can be obtained corresponding to designations (Ia), (Ib), and (Ic) of C₃ H₅ (OH).

The compound of the invention can be in the form of an oil, or it may be solid at room temperature.

Compounds with formula (I) where X and Y represent S are known and can be used as lubricants.

A further object of the invention is to provide a compound with formula (I'):

    R.sub.F --(CH.sub.2).sub.n --X-- C.sub.3 H.sub.5 (OH)!--Y--R.sub.H(I')

where

C₃ H₅ (OH) represents the structures: ##STR7## R_(F) represents a perfluorinated C₄ -C₂₀ alkyl radical or a mixture of perfluorinated C₄ -C₂₀ alkyl radicals;

R_(H) represents a linear or branched C₁ -C₂₂ alkyl radical or a mixture of linear or branched C₁ -C₂₂ alkyl radicals, an aryl radical or an aralkyl radical;

n is between 0 and 4;

X and Y represent ##STR8##

In general, these compounds are used in cosmetic compositions to improve the cosmetic properties. They provide smoothness, gloss and a non-sticky feel to keratinous material such as skin, hair and nails. In addition, some of these compounds are in the form of a colorless oil and can thus be used to produce transparent emulsions.

The invention thus also concerns a cosmetic composition containing at least one compound with formula (I) and at least one cosmetic additive.

The composition can be in the form of an emulsion, milk or cream, oily or oleoalcoholic lotion, greasy or oleoalcoholic gel, ionic or non-ionic amphiphilic lipid based vesicular dispersion, solid stick, paste, spray or aerosol foam.

Depending on the form of the composition into which the compound of the invention is incorporated, the compositions also contain additives which are normal for the selected form.

More precisely, the composition can be a skin or hair milk or cream, a make-up removing cream, lotion or milk, a sun protecting cream, gel, milk or lotion, a shaving cream or foam, an aftershave lotion, a shampoo or conditioner, a body deodorant, a toothpaste, a lacquer, a hair dye composition, a hair perming composition, a lip care product or a nail care product.

The cosmetic composition can also be used as make-up for eyelashes, eyebrows, nails, lips or for skin in epidermal treatments, a foundation, lipstick, eye-shadow, blusher, eyeliner, mascara or nail polish, for example.

Compounds with formula (I) represent 0.1% to 25%, preferably 0.1% to 15% of the total composition weight.

Examples of normal cosmetic additives which can be present in this type of composition are the usual fatty substances, organic solvents, silicones, thickeners, softeners, UV-A or UV-B or broad spectrum solar filters, anti-foaming agents, moisturising agents, humectants, fragrances, preservatives, surfactants, fillers, sequestrating agents, emulsifiers, anionic, cationic, non-ionic or amphoteric polymers and their mixtures, antiperspirants, alkalinizing agents, dyes, pigments, propellants, anti-oxidizing agents and free radical absorbers.

More precisely, examples of fatty substances are oils or waxes or their mixtures, fatty acids, fatty alcohols, fatty acid esters such as C₆ to C₁₈ fatty acid triglycerides, vaseline, paraffin, lanolin, or hydrogenated or acetylated lanolin.

Examples of oils are inorganic, animal, vegetable or synthetic oils, in particular vaseline oil, paraffin oil, castor oil, jojoba oil, sesame seed oil, and silicone and isoparaffin oils and gums.

Particular examples of animal, fossil, vegetable, inorganic or synthetic waxes are beeswax, Carouba wax, Candelilla wax, ozokerites, microcrystalline waxes and silicone waxes and resins.

Examples of organic solvents which are generally used in cosmetic compositions are C₁ to C₆ low monoalcohols or polyalcohols such as ethanol, isopropanol, propyleneglycol, glycerol, sorbitol, ketones such as acetone, esters such as butyl acetate or ethyl acetate, and toluene.

Examples of thickeners are cellulose derivatives, polyacrylic acid derivatives, guar gum or carouba gum, and xanthane gum.

Examples of surfactants are non-ionic surfactants such as alkyl(C₈ -C₂₄)polyglycosides where the number of glucoside units is between 1 and 15, and non-ionic polyglycerolated surfactants.

Particular alkylpolyglycosides are those sold under the trade name APG, such as APG 300, APG 350, APG 500, APG 550, APG 625 and APG base 10-12; and products sold by SEPPIC under the trade names TRITON CG 110 and TRITON CG 312.

The polyglycerolated compounds are derivatives resulting from condensation of 1 to 10, preferably 2 to 6 moles of glycidol with one mole of C₁₀ -C₁₄ alcohol or alphadiol, or with C₁₂ -C₁₈ fatty acid diglycolamides, such as those described in French patents FR-A-1 477 048, FR-A-2 328 763, FR-A-2 091 516 and FR-A-2 169 787.

The vesicular dispersions of ionic or non-ionic amphiphilic lipids mentioned above can be prepared using normal techniques, for example as described in "Les liposomes en biologie cellulaire et pharmacologie", Ed. INSERM/John Libbery Eurotext (1987), pp 6-18.

For toothpaste compositions, the usual additives can be used such as polishing agents, for example silica, active ingredients such as fluorides, for example sodium fluoride, and optional sweetening agents, for example sodium saccharinate.

The following examples illustrate the invention and do not in any way limit its scope.
